Quality You Can Verify
Every product we ship is tested in our own laboratory and backed by the documentation to prove it.
Quality You Can Verify
Quality in our industry is not a slogan; it is a chain of evidence. From the steel we source to the certificate that travels with each consignment, our quality system is built so that buyers, inspectors, and engineers can verify exactly what they are receiving.
Certified Materials & In-House Testing
Certified Materials
Raw material of certified grade, with chemical composition — including coating zinc — backed by EN 10204 3.1 certificates.
In-House Testing Laboratory
Hardness, proof load, wedge load, tensile strength, head soundness, elongation, and yield strength testing, all in-house.
Zinc Coating Verification
Verification of zinc chemical properties and careful control of process timing for consistent, corrosion-resistant finishes.
Calibrated Instruments
All gauges, micrometers, and vernier calipers periodically calibrated by government-approved agencies.
Standards We Follow
German industrial standard defining fastener dimensions, tolerances, and mechanical properties.
International standard ensuring consistent quality, fit, and performance across every market we serve.
American mechanical engineering standard covering fastener design, threading, and load performance.
Mill test certification verifying material composition and mechanical properties for every batch supplied.
Documentation & Traceability
Certification & Documentation
Mill Test Certificates (MTCs) to EN 10204 3.1 with a test report accompanying every dispatch.
Batch Traceability
Every batch can be traced through its own manufacturing history, from raw material to finished product.
A mill certificate is a promise in writing. We do not issue one we cannot stand behind.
What's On Paper Is What Arrives
For our export customers in particular, this discipline is what makes us a dependable long-term partner: when a shipment clears customs and arrives on site, what is written on the certificate is exactly what is in the box.
